Title: Method for controlling hydraulic piston pumps, in particular for thick materials, such as for example concrete
Inventor: SPICKA ROLAND
IPC: F04B1/32
Filed: 1982-06-16
Abstract: The invention relates to a method for controlling hydraulic piston pumps, in particular for concrete, by means of one or more hydraulic pump(s), the delivery volume of which can be preset, for controlling the piston cylinder(s). The path of the fresh concrete through the piston pump is in this case guided by a hydraulically driven reversing system. Two-way valves required in this case are disadvantageous, since they lead to excessively strong switching impacts and thus stress the pump mechanics, and also lead to considerable noise disturbance in some cases. The aim is to provide a method which permits a low-impact reversal of the movements of the dry cylinders. The solution provides for a hydraulic pump, driven in the same direction of rotation, to deliver a hydraulic medium, starting from a zero delivery volume, with a constantly repeating reversal of the delivery direction. The pulses for switching the delivery direction are transmitted time-dependently or path-dependently when preset maximum and minimum volumes are reached. The delivery volume is thus continuously changed from plus "max" to zero and from zero to minus "max". Oblique-axis pumps, oblique discs and radial piston pumps are preferably used. <IMAGE>

Title: Hypocycloidal gearing for a reciprocating-piston engine
Inventor: SCHEIGER MARTIN
IPC: F02B41/04
Filed: 1982-08-28
Abstract: A hypocycloidal gearing for a reciprocating-piston engine, in particular an internal combustion engine, can be completely balanced statically and dynamically by means of a first counterweight and a second counterweight and, if required, an additional weight for compensating the reciprocating weight. This is then a slider-crank mechanism which can, for example, be described by the kinematics of the 2:1 hypocycloid. In this arrangement, a ring bearing engages over a circular-disc-shaped secondary eccentric. This rotates in the opposite direction and at twice the speed with respect to a primary eccentric which is connected in terms of rotation to the main shaft. According to the invention, this primary eccentric comprises a crank offset, for its part made up of the crank webs and the crank pin between the latter. The crank pin has a considerably smaller diameter than a circular primary eccentric corresponding in its eccentricity to the crank offset. As a consequence, the secondary eccentric and the ring bearing can also be of considerably smaller design. This leads to lower and hence smaller counterweights.

Patent DE-3319409-A1 (DE)
Title: Valve for a pressure-boosting system
Inventor: OPLAENDER JOCHEN DIPL ING
IPC: F04B49/02
Filed: 1983-05-28
Abstract: The invention relates to a valve for a pressure-boosting system for the feeding of liquid, especially water, to a consuming unit at as constant a pressure as possible. A pressure-accumulating expansion vessel opens out between pump outlet and consuming unit. Between the junction and the pump outlet is a first valve aperture by means of which any return flow to the pump is prevented in the event of a pump shut down. At the junction or between junction and expansion vessel is a second valve aperture which is closed when the pump is switched on. The second valve aperture is bridged by a bypass with a diameter smaller than that of the second valve aperture and a pressure switch switches the pump on when the liquid pressure on the consuming unit side drops below a predetermined value. Both valve apertures can be closed by a single valve control element which closes the two valve apertures alternately. The connection for the consuming unit branches off between the two valve apertures.

Title: Electrically tiltable rearview mirror
Inventor: LAUER WOLFGANG DIPL ING
IPC: G02F1/1347
Filed: 1983-09-01
Abstract: In an electrically tiltable rearview mirror for motor vehicles, whose effective reflectivity is selectively variable by means of electrical drive of a liquid crystal cell, said cell is alternately controlled in states of different transmission by means of a periodic sequence of control voltage pulses, said transmission assuming minimum value at least for some of the time. The pulse sequence frequency of the control pulses is adequately large for its chronological and local variations of the reflectivity of the mirror not to be capable of being perceived any more. By dividing the control electrodes into a multiplicity of parallel strip electrodes which can be successively driven in groups, a strip-shaped structure of the local transmission of the liquid crystal cell is achieved, which extends beyond the field of vision of the mirror so that in total a chronological and spatial averaging of the reflectivity results. By overlaying two such strip structures of two optical liquid crystal cells which are connected one behind the other, said strip structures extending beyond the field of vision of the mirror with a time delay, and/or by varying the length of the period of the control voltage pulses whose pulse duration corresponds at least to the switching-on time ta of the liquid crystal cell (N), the effective reflectivity of the mirror can be continuously varied within broad limits.

Title: Long-term care plant pot
Inventor: BLOCK HUBERT K
IPC: A01G31/02
Filed: 1983-09-01
Abstract: The invention relates to a long-term care plant pot for earth/water and water/earth combination cultivations or hetero-cultivations, which pot consequently functions as connecting element between two plant cultivation types of a plant. The plant pot containing the root ball of the hetero-plant is arranged in an overpot. The space between plant pot (3) and overpot serves as water store. Double-walled edge chamber elements of the pot are provided with slots or openings and partly provided with clay granulates (7) and/or phenolic resin foam parts (5<a>). The edge chamber elements as mentioned serve the plants as a watering chamber (1) for growing into from the earth region into the water region, and also as a root aeration chamber (2) and as a root-ball permanent moistening chamber (5, 5a). The maximum water level between plant pot and overpot is envisaged to be up to half the height of the plant pot. A special feature of the pot is that the water supply is arranged next to (around) the root ball, and also that plastic net products (17) with clay granulate underlayer (7) form the chambers (double-wall construction). Finally, the good manufacturability and packing-favourable stackability of the pot models (Figs 1, 5, 6, 7) may be stressed. The evaporation losses from the earth root-ball region (Fig. 2) are limited to a minimum by clay covering granulates. <IMAGE>

Title: Turn-off thyristor module
Inventor: YAMAGAMI KOZO
IPC: H01L29/74
Filed: 1983-10-11
Abstract: A thyristor module combined as a single component comprises one or more turn-off thyristors (10) and one or more flywheel diodes (20) which are connected in antiparallel with the thyristors. A turn-off thyristor and a flywheel diode are mounted on a common electrode plate (33) which is mounted on an insulating substrate (35). The individual elements are interconnected by an internal wiring system (30) and have external leads (38, 39, 40) which are mounted on the insulating substrate. The module can be switched on and off by applying a voltage between anode and cathode and a gate voltage between gate and cathode via the external leads. If a turn-over voltage is applied to the turn-off thyristor, the flywheel diode becomes conducting. Since the module has an internal wiring system, the inductance of the wiring system is extremely low. <IMAGE>
